Description

전열 매트용 세라믹{omitted}Ceramic for Heat Transfer Mats {omitted}

본 발명은 전열 매트에 부착된 세라믹에 관한 것으로서, 특히 온도에 의하여 색깔이 변화하는 도색재를 세라믹에 도포하여 원적외선이 발산되는 세라믹의 가온상태를 시각적으로 간단히 판단할 수 있을 뿐만 아니라, 그로 인하여 세라믹의 가온상태를 용이하게 조절하여 전열 매트에 인가되는 전기를 절약할 수 있꼬, 시각적으로 고급화를 꾀하여 상품의 판매효과를 향상할 수 있는 전열 매트용 세라믹을 제공하는 것이다.The present invention relates to a ceramic attached to a heat transfer mat, and in particular, by applying a colorant that changes color due to temperature to the ceramic, it is not only possible to visually easily determine the heating state of the ceramic that emits far-infrared rays. It is possible to save the electricity applied to the heating mat by easily adjusting the heating state of the heating mat, to provide a ceramic for the heat transfer mat that can improve the sales effect of the product by visually advanced.

일반적으로 전열 매트는 주로, 전기로 발열되도록 한 전열선이 구비된 발열부와, 상기 발열부의 인체 접촉을 방지하도록 차단부 등을 적층, 마감하고, 상기 발열부의 온도를 조절하도록 한 온도 조절기와 매트가 일측에 상기 온도 조절기가 접촉되도록 한 전원연결 소켓과, 상기 차단부에 다수 부착된 원적외선용 세라믹을 구비하였다.In general, the heat transfer mat mainly includes a heating unit provided with a heating wire to generate electricity, a thermostat and a mat for stacking and finishing a blocking unit to prevent human contact with the heating unit, and controlling the temperature of the heating unit. On one side was provided with a power connection socket to contact the temperature controller, and a far-infrared ceramic attached to the blocking unit.

이와 같이 구성된 일반적인 전열 매트는 특히 겨울철에 난방이 부족할 경우 사용됨은 물론이고, 더불어서 발열부에 의하여 가열된 세라믹에서 방출되는 다량의 원적외선에 의하여 건강증진을 도모하였다.The general heat mat constructed as described above is used not only in the case of lack of heating in winter, but also promotes health by a large amount of far infrared rays emitted from the ceramic heated by the heating unit.

이때, 상기 세라믹은 가열되어야만 원적외선을 다량으로 발산하여 사용자의 건강상의 효과를 낼 수 있는 것이다.At this time, the ceramic must be heated to emit a large amount of far infrared rays to have a health effect of the user.

상기 일반적인 전열 매트는 온도 조절기에 표시된 특정 온도로 조절하여 그 발열온도를 조절하였다.The general heat mat was adjusted to a specific temperature indicated by the temperature controller to control the exothermic temperature.

그러나 상기 온도 조절기로 조절하는 전열 매트의 발열온도는 발열부의 발열량을 따져서 그 온도를 조절하는 것으로서, 상기 세라믹이 온도 조절기로 조절된 온도로 적층부에서도 발열부와 같이 발열된다는 것은 아니다. 또한 전열 매트가 사용되는 조건 즉 통풍의 유무, 매트에 이불을 덮거나 그렇지 않은 경우, 차가운 바닥이나 일정 온도로 덮혀진 바닥 등 여러가지 외부조건에 따라 사용자가 직접 체감하면서 온도 조절기로 매트의 온도를 적절히 조절하거나 일정장소에서 여러번 사용한 경험에 의하여 온도 조절기로 특정 온도에 맞추어 사용하였다.However, the heat generation temperature of the heat transfer mat controlled by the temperature controller is to adjust the temperature based on the amount of heat generated by the heat generating unit, and the ceramic is not heated like the heat generating unit at the temperature controlled by the temperature controller. In addition, according to the conditions under which the heat mat is used, that is, whether there is ventilation, or if the mat is covered with a blanket or not, a cold floor or a floor covered with a certain temperature, the user may feel the temperature and adjust the temperature of the mat appropriately. Depending on the experience of using it several times in a certain place, it was used as a temperature controller to a specific temperature.

따라서 상기 온도 조절기를 조절하므로써 적층부에 부착된 세라믹이 가열되어 사용자의 건강에 도움이 될만큼 충분한 원적외선을 방사한다는 믿음의 신뢰성이없으며, 또한 이와 같은 신뢰성을 불식하기 위하여 온도 조절기를 필요 이상으로 높게 조절하며는 그에 따른 전기 소비량이 많이 증기되어 소비자의 가계비에 부담을 주는 문제점이 있었다.Therefore, there is no confidence that the ceramic attached to the lamination by heating the thermostat radiates enough far infrared rays to help the user's health, and the thermostat is higher than necessary to dispel such reliability. There was a problem in that the electricity consumption is a lot of steam to adjust accordingly to burden the household expenses of consumers.

본 발명은 이와 같은 문제점을 감안하여 안출한 것으로서, 전열 매트에 사용되는 세라믹에 온도에 따라 색이 변경되는 도포재를 도포하여 세라믹에 전달되는 온도를 시각적으로 판단할 수 있도록 하므로써, 그 상태에서 건강상 필요한 원적외선이 세라믹에서 다량으로 방출된다는 것을 신뢰케 하며, 그로 인하여 불필요하게 많은 전기가 소비되는 것을 방지하는 효과를 얻고, 또한 원하는 온도에 원하는 칼라를 낼 수 있는데 그 목적이 있는 것이다.The present invention has been made in view of the above problems, by applying a coating material that changes color according to the temperature to the ceramic used in the heat transfer mat to visually determine the temperature transmitted to the ceramic, in that state health The objective is to make sure that the far-infrared rays required by the phase are emitted from the ceramic in large quantities, thereby obtaining an effect of preventing unnecessary consumption of electricity, and also producing a desired color at a desired temperature.

따라서, 상기 도포재(60)의 색상변화로 상기 세라믹(20)이 소정의 온도로 가열되어 원적외선을 방출하고 있다는 것을 사용자가 확실하게 짐작 할 수 있게 되며, 그에 따라서 온도 조절기(40)를 적절하게 조정한다.Therefore, the user can be sure that the ceramic 20 is heated to a predetermined temperature to emit far infrared rays due to the color change of the coating material 60, and accordingly the temperature controller 40 can be properly adjusted. Adjust

이때, 상기 세라믹(20)은 가열된 상태에서 사용자의 건강을 증진할 수 있는 다량의 원적외선을 방사 하므로, 상기 도포재(60)는 원적외선이 다량 방출되는 시점에서 그 색깔이 변화되는 것을 사용한다.At this time, since the ceramic 20 emits a large amount of far infrared rays that can promote the health of the user in a heated state, the coating material 60 is used that the color is changed when the large amount of far infrared rays are emitted.

그리고 도 3과 같이 본 발명은 도포재(60)를 도포한 세라믹(20)과 세라믹(20')등과 같이 원적외선을 방출하는 부재와 결합하여 사용하게 되면, 상기 세라믹(20')은 섭씨 30도 이상부터 원적외선을 다량으로 방출하므로, 세라믹(20)에서 다량의 원적외선이 방출되는 가온상태는 물론이고, 상기 세라믹(20)에서 다량의 원적외선이 방출되기 전의 가온상태에서도 효과적으로 다량의 원적외선을 방사할수 있게 된다.And as shown in Figure 3 when the present invention is used in combination with a member that emits far infrared rays, such as ceramic 20 and ceramic 20 'coated with a coating material 60, the ceramic 20' is 30 degrees Celsius Since it emits a large amount of far-infrared from above, as well as the warming state in which a large amount of far-infrared radiation is emitted from the ceramic 20, it is possible to effectively radiate a large amount of far-infrared radiation even in the warmed state before the large amount of far-infrared radiation is emitted from the ceramic 20. do.

또한, 상기 세라믹(20')에도 도포재(60)를 도포하여 사용하도 무방하며, 이때, 상기 도포재(60)는 세라믹(20')에서 다량의 원적외선이 방사되는 온도에서 그 색깔이 가변되는 것을 사용함이 바람직하다.In addition, the coating material 60 may also be applied to the ceramic 20 ', and at this time, the coating material 60 may vary in color at a temperature at which a large amount of far infrared rays are emitted from the ceramic 20'. It is preferable to use one.

이와 같이 본 발명은 전열 매트에 사용하는 세라믹의 온도에 따라 색깔이 가변되는 도포재를 도포하므로써, 일정 온도 이상에서 다량의 원적외선을 방사하는 세라믹의 상태를 사용자가 간단하게 판단하여 전열매트를 사용시 편리성을 증진하여, 세라믹을 가온하기 위하여 필요이상으로 전열매트에 인가되는 전기의 낭비 요인을 제거할 수 있는 효과가 있다.As described above, the present invention applies a coating material whose color varies depending on the temperature of the ceramic used in the heat transfer mat, so that the user can easily determine the state of the ceramic that emits a large amount of far-infrared radiation at a predetermined temperature or more, and is convenient when using the heat transfer mat. By improving the sex, there is an effect that can eliminate the waste of electricity applied to the heat transfer mat more than necessary to heat the ceramic.

또한, 온도에 따라 가변되는 도포재에 의하여 소비자로부터 상품의 구매의욕을 증감하며 판매량을 향상할 수 있는 효과적인 발명이다.In addition, it is an effective invention that can increase and decrease the willingness to purchase goods from the consumer by the coating material that varies depending on the temperature.
